Question

好吧，我到处寻找解决方案，但没有一个能奏效。昨天，我的XAMPP工作得非常好。今天，我试图开始我的MySQL服务，它不起作用。让我更具体一点：这是XAMPP日志：

这是错误日志：

Apache工作正在运行btw。我尝试过的事情：

删除ibdata1文件。更改my.ini中的端口。 Skype没有运行。停止万维网发布服务。

Answer 1

好的，我自己弄清楚了。所以我查看了Windows事件查看器，发现一些错误来自MySQL。我点击了最近的一个，发现了这个。

mysqld.exe：表'。\ mysql \ db'被标记为崩溃，最后（自动？）修复失败

我替换了所有db文件：db.frm，db。 MYD和db.MYI（以防万一）将这些内容复制到桌面上。而且中提琴再次起作用。所有的数据都存在，甚至是我记得昨天插入的数据。

Answer 2

在我的情况下，这是因为我安装了MySQL Workbench，它也使用端口3306自己安装MySQL。因此，有2个MySQL安装，并且都尝试使用端口3306。Workbench似乎优先。

更改XAMPP MySQL以使用端口3308是最简单的。

在XAMPP控制面板中：停止Apache和MySql。
编辑my.ini（在某些MySql安装中为my.cnf；在其他my.ini中）
它的位置将取决于您安装XAMPP的位置。在我的系统上，我在T:\xampp\mysql\bin\my.ini上找到了它。（我的系统上MySQL Workbench的类似文件位于``）
搜索3306（或port）；替换为3308。
我在2个地方用port = 3306替换行：port = 3308
保存
从XAMPP控制面板：启动Apache和MySql

Windows MYSQL上的XAMPP将启动然后突然停止，但APACHE正常工作
